MACHINE FOR MAKING BRUSHES.

To all whom it may concern."

Be it known that I, JosEr BAER, a subject of the King of Nurtemberg, and resident of VVeingarten, in the Kingdom-of /Viirtemberg and Empire of Germany, have invented certain new and useful Improvements in Machines for Making Brushes, ofwliich the following is a specification.

This invention relates to improvements in brush making machines and the novelty resides in the peculiar construction and com binationof parts hereinafter more fully described and then particularly pointed out in the appended claims.

the drawings, the numeral 1 designates the lower portion of the frame, and 2 the upper portion, as shown more clearly in Fig. 3.

In theframe 1 is j ournaled the main operating shaft 3 which derives its motion from a pulleye, preferably loose on the shaft and designed to be connected therewith and disconnected therefrom by suitable clutch mechanism,in this instance a beveled clutch disk 5, under tension of a'spring 5 and operated by levers 6 and 7 from any suitable source. The rotary motion of shaft 3 is transmitted to a vertical shaft 11 through bevel gears 10 and 10, and this vertical shaft 11 drives the various parts of the machine bymeans of bevel gear 8 and cams 12 and 13, all on said vertical shaft 1 1 in the manner hereinafter described. The bevel gear 8 meshes with a bevel gear 9 fast on a horizontal shaft 1 1 journaled in the upper frame, and on this shaft are secured two cams 15 and 16. The cam 16-has cam grooves 16 and 16 in its opposite faces as indicated in Fig. 19.

A lever 17 pivoted at 17 to the frame 2 is provided with a pin or like projection at 18 which travels in the cam groove 16 as clearly shown in Figs. 1 and 19. A rod or pitman 19 is pivoted at one-end to the free. end of lever :17, the lower end of said pitman being connected to a slide 20 moving ver tically in a guide 21, the slide in turn bein connected to and operatin the tuft an staple inserting plunger 22 iiirough the medium of its stem 22 hereinafter more fully described.

The cam groove 1 6 hereinbefore referred to is engaged by a pin23 on a lever 23 pivoted at 23* to the frame 2 whereby the lever is operated in a manner similar to the lever 17. The free end of this lever 23 is connected by a link'24 with a slide 25 bearing a nozzle 26 (see Figs. 1 and 2) the slide 25 being guided by the guide 27 in which it slides. A slotted bar- 28 is also connected to the lever 23 by means ofthe arm 23 and pin 23 (see Fig. 18), which slotted bar operates the mechan ism for bending and cutting off the wire as hereinafter described in detail.

A lever 29, pivoted at 29 is operated by the cam 15 by its pin 30 engaging the groove The free end of this lever is connected by slink or rod 30 with one arm of a bell crank lever 31, the other arm f of which carries-a pawl 33 adapted. to engage the teeth of a ratchet wheel 32 (see Fig. 3) by which an intermittentmotion is imparted to the feed rolls 34 and 35 which draw oil or feed the wire 36 as shown in detail in Figs. 4 and 5. The w1re as shown is wound on a drum or reel 37 journaled in standards 27*.

The pawl 33 is held elevated by means of a spring 33 acting against its under side as seen in Fig. 3. To a pin 39* carried by the which has .a link connection 47 by which a reciprocatingmovement isimparted to the slide 46. Said shaft 41 also carries an arm 48 which is connected by a rod or link 50 with an arm 51 by which rocking or osoillating movement is imparted to the curved tuft separator 49 as shown more clearly in Figs.

1 and 18. Connected with the arm 42 is a bar or rod 52 which transmits motion to the pivoted arm 53.

The cam disk 12 has a notch 54'adapted to beengaged by a lever arm. 55 carried by a shaft 57 which carries an arm 58. This arm has an end or portion extending between'two rings or collars 61 and 62 fast on a rod 59 which is mounted to slide vertically in orificed lugs on the guide 27 Between the said lugs the rod 59 passes throu h the openings in the horizontal arms of a 'arne 60. The rod 59 is free to move longitudinally in the frame 60 but is non-rotatable with res ect thereto. A spring 56. encircles said re 59 and bearing against a collar 59 thereon tends to keep said rod normally depressed. On the lower part of this rod 59 is carried an index 63.

Secured to the frame 60 is a bar or projec tion 64 which has an angularly turned '01' tion provided with an inclined edge or ace portion as shown in the detail view Fig. 21. The upper end of the slide 25 to which the rod 24 is connected is extended laterally in the form of a lug 65, (see Fig. 21) so that as the slide moves downwardly this lug will engage the cam rojection 64, and thus the frame 60 will is swung slightly in a horizontal plane on a vertical axis, and against the tension of the sprin 66. This spring encircles an upri ht 66 w ich passes through an arm 68 ext-en ing from the ring or collar 61 and has one end connected to said frame 60 and the other end to guide 69 so that the roe tary movement places the sprin under tension. The rotary movement of the arm 68 is limited by-a stationary guide 69 (Fig. 18). A bell crank. lever 71 pivoted at 70, has a pin or projection 7 0* which engages the cam contact therewith by the spring 85.

groove 13 of the cam 13 (see Fig. 7). The other arm of this bell crank lever has a slotted portion 71 which is engaged by a pin. or projection 72" on the bar 72 which is con nected with a member 73 bf inverted U-- shape, as shown in Fig. 8. This member 73 moves in and cooperates with the bending and cutting mechanism, which will now be described (see more especially 12 and 15), 74 is a frame or pla'te','secured to the guide 27 as best seen in Fig. 14. i

The numeral 75 designates a cutter and presser slidable in the frame or plate 74 and which is actuated by the bar 28, and which 1' moves at right angles to the wire guide 76 and shears off a proper length of wire by the actionof the edge 77. This piece of wire is then pressed by the recessed portion 78 over a former 79 which extends horizontally through and is .fixed in a, recessed guide 80) carried by a bracket 80, see Fig.8.

When the wire is cut off the slide 73 is drawn back. When the loop or staple 81 is formed over the former, then the slide 73 which passes over the former, brings it in front of the socket 126 of the nozzle 26 when it drops from the saddle 79, when it is forced down by the plunger 22.

83 is a receptacle for bristles 82, said receptacle has a movable side wall 84 which is reciprocated by means of a pivoted lever 85 W1iCl1 is pivoted between its ends to an arm on the machine frame and is pivot-ally com nected at its upper end with the slidable rod 85 secured'to "the said side wall 84. An expansion spring surrounds said rod 85 between its bearing in the machine frame and the lever 85 and by its expansion tends to i draw the movable side 84 away from the bristles. The opposite end of lever 85 is provided with a roller 95 which contacts with a. cam faceon a wheel95 secured to the shaft43. I the movable side 84 of the bristle receptacle is alternately driven against the ends of the bristles by the cam 95 and withdrawn fp plm is On rotation of the said cam wheel reciprocation of the movable slide 84 keeps the endsof the bristles"82 e en. is reciprocable through a s ot in the lower 'rear ortion" of the bristle receptacle 83.

A slide 86 This slide is actuated by an arm 98 on a rock{ shaft 97.

The shaft 97 is rocked by anarr'n- 102 having a pin 96 which enters a cam slot.

bristle separator as and in connection with rod operates the same to separate the tufts of bristles from the mass of bristles in receptacle 83. 92'and 93 are parallel horizontal bars spaced apart andbetween them the bristles are transferredby the slide 46 from the bristle receptacle to the stapling The parallel bars 94 swing loosely in front of the tuft of bristles as the said tuft is transferred and serve to keep the tuft compacted during its transfer. 100 is the brush stock and 101 designates the extensions of the staple.

' The tuft transferring slide 46, shown clearly in Figs. 1', S), 11 and 13 is'mounted for reciprocation, and. at the place where the bristles enter into the conic guide this slide serves by means of its notch on the side of the cutout part of the socket of the nozzle as a guide for the staple 81, and for the plunger 22. I

The operation of the machine is as follows: The bristles 82 are placed in the receptacle 83 and the side wall 84 is reciprocated against one end of the bristles thus serving to keep their ends even and to keep' them loosened up so that they may constantly fall toward the bottom of the chute. The shaking slide 86 is actuated to further loosen the bristles and to feed them positively toward the forward, lower end of the chute where they may be acted upon by the tuft sepa- The tuft-separator 49 is now raised by means of the levers 87 and 88. When the tuft-separator 49 is-raised, it pushes by means oflever 51 through the medium of the bar 50 between the bristles and separates a bunch. This bunch is thus deposited in front of the tuft -transferring slide 46 and is pushed forward thereby n1ov-.

ing between the bars 92 93. Two loosely suspended parallel bars 94, Fig. 1, keep the bunch of bristles compact and prevent its separating until it lies in the nozzle 26. At

. the same time a piece of wire 36 has been cut off by the cutter 77, and by the aid of the recess 78 of the part pressed over the saddle 79. The slide 73 now guides the staple 81 through the groove in the guide 80 until it is under the plunger 22 exactly over the bristles (Fi s. 10 and12). The plunger is now pressed down and pushes the staple 81 and the bristles through the nozzle 26. This nozzle is provided with a cone-shapedv lower portion seen best in Fig. 9. The notch in the forward end of the slide 46. (see Fig. 11) serves as a guide to let in the staple (see Fig. When the loop is put .into the brush stock 100, the ends are forced in and the bristles held firm in the manner of a hook. The extensions 101 of the loop are likewise pressed into the wood so that the bristles are so firmly hold thatit is impossible to pull them out by hand. The brush stock 100 is moved by the operator himself, 74 is an indicator on the machine. Thspressure of the spring 56 always keeps theindicator in thelowest position directly under the nozzle, and this position is to be adjusted when the first hole is filled, the indicator being first placed in the hole and then the machine set in motion: When the cam 12. revolves the lever-55 is pressed'up, the bar 57 and the crank 58 turned up so that the indicator comes into its highest position. If now the nozzle goes down, the projection '65 of its slide presses on the sloping edge of the plate so that the holes can be placed in various positions Without the method of operation being altered.
